What advice would you recommend for a student aiming to secure their first BDR role in a B2B SAAS.

Hi, good people. I've decided to start preparing myself to join a tech startup in their growth stage to learn more about the tech industry and master my sales skills. Does anyone have any advice on how to approach BDR managers or directors for an opportunity on their team? Or, what would you do if you were in my position? Any comments or suggestions are welcome :)
